NEW YORK -- New York's new mayor says, "Big dreams are not a luxury reserved for a privileged few."

Bill de Blasio was sworn in today, vowing to "give life to the hope of so many in our city." He thanked his family, his supporters and the city for "taking on the elite" and pushing for change.

Former President Bill Clinton administered the oath, as thousands of people braved cold New Year's Day temperatures to salute the new mayor.

The Democrat is pledging to pursue a sweeping liberal agenda as he takes over from Michael Bloomberg, who was mayor for 12 years and who was among those attending the ceremony.

One speaker after another at today's event railed against the city's inequality. They delivered sharp rebukes to Bloomberg, though they never mentioned him by name.
